Hints

Silver Chao egg

Go to the Mystic Ruins. Go to the water fall located in the middle of the Adventure Field. Push the stone that is jutting out of the wall to the right of the water fall. A silver egg will fall from behind the waterfall and float to shore. When it hatches, a silver Chao will be born.

Golden Chao egg

Go to the Station Square area. Then, go to the area when you fought Chaos for the first time. Look to the side of the City Hall entrance to find an egg shaped rock. Take the rock to the building to the left from City Hall. Walk to the window to see a golden Chao egg. However, if you try to take it the front door will lock. Replace the egg with the rock and the door will unlock, allowing you to leave with the egg. When the egg hatches, a golden Chao will be born.

Black and blue Chao egg

Go to the egg carrier. Then, go the jail area where Amy was kept. In the cell next to where she was held is a black and blue egg. Step on the switch to open the door. Take the egg to the garden. When it hatches, a dark grey and dark blue Chao will be born.

Special Chao

Collect at least 100 emblems to get access to a special section called the Black Market on the Dreamcast Network site. A Special Chao can be downloaded from this area.

Get all five Chaos Emeralds with the Chao

To get all five of the Chaos Emeralds that you can get with the Chao, you need to log on to the Dreamcast Network site and go to the Chao Daycare Section. Download one of the Chaos that are 999 in all four categories. Return to your Chao Garden and race him in a Chao Race. He will easily defeat all the other Chao. Repeat this on all five races to get the five possible Chaos Emeralds.
